LOW-LEVEL IMI TIUIIJE'L CONDENSER.

Application led March 15, 1923. Serial No. 625,201. y

To all whom t may concern:

Be itknown that I, JOHN F. KIRGAN, a citizen oi' the United States, a resident of Phillipsburg, county of Warren, and State of New Jersey, have invented a certain L0w- Level Multijet Condenser, of which the ollowing is a specification accompanied by drawings.

This invention relates to low level multijet condensers, but more particularly to a condenser having regulating means for the water jets and for the diii'user.

The objects of the invention are to enable the flow oi water through each jet to be regulated and controlled, and also to enable the diffuser to be controlled proportionately to the jets. The condenser is thus more efficient and more economical in its use of water.

Further objects of the invention will hereinafter appear and the invention is shown in one of its preferred Jforms in the accompanying drawings, in which- Figure 1 is a longitudinal sectional elevation of a condenser,

Figure 2 is a similar view partly broken away showing some of the parts in a different position, and

Figure 3 is a detail transverse sectional view on the line 3-3 of Figure 1, looking in the direction of the arrows.

Referring to the drawings, the condenser comprises a casing having the lower section or body A, the upper section or inlet head B, the throat piece C, and diffuser casing D to gether forming the diii'user, and the tail pipe E which is adapted to be partially sub merged as usual in the tank or sump (not shown). The diffuser is constructed with a contracted throat formed by the lining piece F in the entrance of the diffuser, which is also the outlet of the condenser casing. A water head G in the upper portion of the casing carries the nozzles H which direct jets or streams of water convergently towards the throat of the ditluser, and the convergent streams of water may be surrounded by the combining tubes, J, between the vanes K of which the steam passes to the streams of water in the usual manner. In this instance, the steam enters the casing at the steam inlet L at the top and the casing is provided with the man hole opening O. The usual vacuum breaker may be provided in the casing P and as shown the ball Q, is

adapted to be raised by water and break the vacuum Within the casing. The vacuum breaker casing is connected to the inlet head B, asby means of the pipe R.

The nozzles H, as shown, are removably mounted in the water head G, and each nozzle is provided with a regulating valve S by means of which the flow through the nozzles may be regulated and controlled. The stems of the valves S are sealed by the glands T and in accordance with. my invention, all the nozzle regulating valves S are simultaneously adjustable. For this purpose, the valve stems are connected to a spider U and an adjusting rod V passing centrally through the water head G has a screw threaded shank W to which the hub of the spider U is threaded. Means are provided for rotating the adjusting rod V and thus raising and .lowering the spider U, which adjusts the nozzle valves S away from and towards the outlets of the nozzles. For adjusting purposes the rod V has a beveled gear X at its upper end meshing with a beveled pinion Y on the spindle Z adapted to be rotated by the crank disc a.

The adjusting rod V as shown, is threaded to a socket piece b on the stem c of a valve d which enters the diffuser. The valve d is preferably in the form of an elongated member having longitudinal grooves e sliding on the guides f. When the adjusting rod V is rotated in one direction or the other for adjusting the nozzle valves S, the valve stem c and diffuser valve IZ will be raised or lowered in accordance with the direction of rotation of the rod V. In Figure 2 for instance, the rod V has been rotated in a direction to cause the nozzle valves S to move inwardly towards the nozzle entrances, while at the same time the screw threaded end of the rod V has entered the socket piece b to a greater extent, thus raising the diliuser valve d further within the throat of the diiluser. Under such circumstanceaas shown in Figure 2, less water is discharged from the nozzles and a more restricted passage is at the same time provided through the diffuser.

I claim:

l. A low level multi-jet condenser, comrising a casing having a diffuser at its ower end and a contracted throat at the en trance of said diffuser, a water head in the upper portion of the casing and a ring orf nozzles on said head for directing converging streams of water to the said throat of the diffuser, each nozzle having an adjustable regulating valve.

2. A loW level multi-jet condenser, comprising a easing having a diffuser at its lower end and a contracted throat at the entrance of said diffuser, a Water head in the upper portion of the easing, a ring of nozzles on said head for directing converging streams of Water to 'the said throat of the diffuser, each nozzlehaving an adjustable regulating valve, and means for simultane ously adjusting all of said regulating valves.

3. A low level multi-jet condenser,co1n prising a casing having a diffuser at its lower end and a contracted' throat at the enrtrance of said diffuser, a Water head in the upper portion of thecasing, a ring of nozzles on said head for directing1`converging streams of Water to the said throat of the diffuser, each nozzle having an adjustable regulatinfr valve, and an adjustable regulating valve for the diffuser.

4. A low level multi-jet condenser, coinprising a casing having a diffuser at its lower end and a contracted throat at the entrance of said diffuser, a water head in the upper portion of the casing, a ring of noz- 'zles on said head for directing converging streams of Water to the said throat of the diffuser, eaoh nozzle having an adjustable regulating valve, an adjustable. regulating valve for the diffuser, and means for simultaneously adjusting all of said nozzle valves JOHN F.
